Write a Python program to sort a list of elements using Selection sort.

According to Wikipedia “In computer science, selection sort is a sorting algorithm, specifically an in-place comparison sort. It has O(n2) time complexity, making it inefficient on large lists, and generally performs worse than the similar insertion sort”.

 

Sample Solution:

Python Code:


def selection_sort(nums):
    for i, n in enumerate(nums):
        mn = min(range(i,len(nums)), key=nums.__getitem__)
        nums[i], nums[mn] = nums[mn], n
    return nums

user_input = input("Input numbers separated by a comma:n").strip()
nums = [int(item) for item in user_input.split(',')]
print(selection_sort(nums))

Sample Output:

Input numbers separated by a comma:
 15, 79, 25, 37, 68
[15, 25, 37, 68, 79]
